Jerusalem, June 12, 2008 A material designed to prevent adhesions following surgery has won for Hebrew University Prof. Daniel Cohn of the Casali Instititue of Applied Chemistry first prize in this year's Kaye Awards for Innovation. The awards were presented during the recent 71st meeting of the Hebrew University Board of Governors.
Prof. Cohn has developed a unique polymer (compounds of high molecular weight) that generate a physical barrier between layers of injured tissues, preventing the formation of adhesions between opposing tissue planes.
Adhesions are abnormal bands of scar tissue that form post-operatively in the treated area and cause organs to bind to one another. Typically, adhesions persist long after the original trauma has healed, attaching organs, nerves, muscles and other neighboring structures. They are formed in approximately 85% of all patients undergoing routine surgical procedures and represent a major source of post-operative complications and deaths.
The generation of adhesions following heart surgery is of special concern, since they may affect cardiac function. Furthermore, in the frequent cases where repeat operations are required, adhesions obscure cardiac landmarks, making the procedure potentially life-threatening to the patient due to inadvertent vascular or cardiac injury.
Already in use is a wide variety of polymers which are foreign to the human body and which are used in direct contact with its organs, tissues and fluids. These materials are called biomedical polymers, and they have contributed significantly to modern medicine. The barrier created by the preventive polymers is required to remain in place for the period during which the adhesions are generated (a few days), and then, gradually degrade and disappear without having any detrimental effect. Additional requirements pertain to handling and suturing properties of the polymeric film..
